The Reds have made an inquiry about exciting young Portugal international Gelson Martins, and are thought to be in preliminary talks over a possible £40million swoop.
Salah's Italian club, Roma, are so far refusing to budge over their £42m valuation on the Egypt international, who Klopp had identified as the pacy winger he desperately wants to provide further attacking options for his side.
Liverpool had a £28m bid rejected for the former Chelsea man, but they will not give up hope on thrashing out a deal with the Italians.
The Serie A side do want to sell but are holding out for their full valuation of a player who scored 19 league goals from a wide position last season.
